Defective mutants were found at an invariant GGLLM motif and at two other highly conserved amino acids. With one exception, they are clustered on the Rpb8p structure. They all impair a two-hybrid interaction with a fragment conserved in the largest subunits of RNA polymerases I (Rpa190p), II (Rpb1p), and III (Rpc160p). This fragment corresponds to the pore 1 module of the RNA polymerase II crystal structure and bears a highly conserved motif (P.I.KP.LW.GKQ) facing the GGLLM motif of Rpb8p. An RNA polymerase I mutant (rpa190-G728D) at the invariant glycyl of P.I.KP.LW.GKQ provokes a temperature-sensitive defect. Increasing the gene dosage of another common subunit, Rpb6p, suppresses this phenotype. It also suppresses a conditional growth defect observed when replacing Rpb8p by its human counterpart. Hence, Rpb6p and Rpb8p functionally interact in vivo. These two subunits are spatially separated by the pore 1 module and may also be possibly connected by the disorganized N half of Rpb6p, not included in the present structure data. Human Rpb6p is phosphorylated at its N-terminal Ser2, but an alanyl replacement at this position still complements an rpb6-Delta null allele. A two-hybrid interaction also occurs between Rpb8p and the product of orphan gene YGR089w. A ygr089-Delta null mutant has no detectable growth defect but aggravates the conditional growth defect of rpb8 mutants, suggesting that the interaction with Rpb8p may be physiologically relevant."xsd:string |
